WILLIAM CHARLES KIDD, OF SUFFERN, NEW YORK, ASSIGNOR TO STANDARDEQUIPMENT COMPANY, OF MAHWAH, NEW JERSEY, A CORPORATION OF NEW JERSEY.

SWITCH-STAND Application filed December 20, 1907.

To all whom it may concern:

Be it known that I, WVILLIAM CHARLES KIDD, a citizen of the UnitedStates, and a resident of the town of Suffern, in the county of Rocklandand State of New York, have invented certain new and useful Improvementsin Switch-Stands, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part hereof.

The object of this invention is to provide a stub or rigid switch standwhich can be unlocked and thrown and then looked again by. what issubstantially a single operation, and to accomplish this end withoutnecessarily having to employ gearing or any complicated mechanism whichwould tend to make the stand bulky as well as expensive to manufacture.

The improvements, as will be seen hereinafter, may be applied inautomatic switch stands as well as in stub stands, but it will sufficefor the purposes of this specification to illustrate and describe theseimprovements in connection with a stub stand, for which they have beenspecifically developed.

In the drawings, Figure 1 is a front elevation of a stub stand embodyingthe improvements, Fig. 2 is a plan view, and, Fig. 3 is a detailedsectional view on a plane indicated by the line 33 in Fig. 2, with thehandle omitted.

Referring to the drawings, the frame or base of the stand is indicatedby the letter a, said frame or base being of any suitable constructionand provided with a bearing 1) for the shaft 0 which, as usual, isvertically disposed and is provided with means (Z upon the lower endthereof underneath the frame for operative connection with the switch.

Projecting from the sh aft and preferably in a substantially horizontaldirection, is an arm f the inner end of which may be forked so as toembrace a block g which is fitted upon a squared portion of the shaft 0and is rigidly secured thereto. The arm f is pivoted to this block by abolt h or the like which extends through both prongs of the fork whilethe other end of the arm may be said to con sist of a projection orprojecting portion which is adapted to engage in a correspondinglyrecessed portion "i of the frame a. In the present case two suchrecessed portions i are shown, the object of which is to permit the armto engage the frame in two positions which correspond respectively tothe two Specification of Letters Patent.

positions of the switch, one against one track and the other against theother track. It will be obvious that when the armf engages the frame ineither one of these recesses 11, the shaft 0 will be prevented fromturning and consequently will lock the switch in the p articularposition to which it has been turned.

Where such a stand as this is employed in a train yard or some otherplace where quickness and ease of operation is desired, it is desirableto have some means whereby the switch may be unlocked and thrown in asingle operation. Moreover, in many of the switch stands now employedfor this purpose and particularly in stub stands, it is not onlynecessary to perform more than one operation to accomplish this end, butthe construction of such stands involves the swinging of the operatinglever around in a more or less horizontal plane, which is undesirable inmany cases on account of the cramped space in which it is oftentimesnecessary to locate these switches. The present improvements havetherefore been developed with the object of giving the operating lever amovement in a single plane, preferably a vertical one, as well as toeffect through the swinging of this lever the unlocking of the switchand the throwing thereof, and also the subsequent locking again of theswitch, in a single operation. \Nith all of these objects in view, alever It has been provided and is pivoted near the lower end of thestand at Z, and, as will be seen, is arranged to swing in asubstantially vertical plane. This lever is provided with a slot throughwhich the free end of the arm f extends, and the slot is so shaped thatthe first movement of the level will effect a lifting of the free end ofthe arm so as to disengage it from the recess i, while the furthermovement or swing of the lever will cause the arm to be swung over andto drop into the other recess i, thereby turning the shaft 0, andthrowing and locking the switch in its other position. It has been foundthat a slot which is approximately pear-shaped as illustrated in thedrawing will sulllce to produce the necessary movement of the arm 7,such slot, or a portion of such slot, obviously constituting a cam whichoperates upon the arm f to produce the movement desired.

It is, of course, possible to provide means as illustrated at m (Figs. 2and 3) through which a padlock or the like may be passed in order topermanently lock the arm in one of the recesses i and therefore to lockthe switch in its turned position indefinitely. Hora over, otheradditions or changes may be made 'in the construction shown anddescribed without departing from the spirit of the invention.

I claim as my invention'.

1. In a switch stand, the combination of a frame, a shaft rotatabletherein, an arm projecting from the shaft and adapted to lock the shaftfrom turning in the frame, and means to unlock the shaft and turn it ina single operation.

2. In a switch stand, the combination of a frame, a shaft rotatabletherein, an arm projecting from the shaft and adapted to lock the shaftfrom turning in the frame, and a lever pivoted to swing in a singleplane and adapted as it is moved in said plane to unlock the shaft andturn it.

3. In a switch stand, the combination of a frame, a vertical shaftrotatable therein, an arm projecting substantially horizontally from theshaft and adapted to lock the shaft from turning in the frame, and alever pivoted to swing in a vertical plane and adapted as it is moved insaid plane to unlock the shaft and turn it.

4. In a switch stand, the combination of a frame, a shaft rotatabletherein, an arm pivoted thereto and adapted to lock the shaft fromturning in the frame, and a lever having a slot through which said armextends whereby, as the lever is moved, the arm is unlocked from theframe and turns the shaft.

5. In a switch stand, the combination of a frame, a shaft rotatabletherein, an arm piv oted thereto, a projection upon the arm to engagethe frame, and a lever having a slot through which said arm extendswhereby, as the lever is moved, the projection is disengaged from theframe and the shaft is turned.

6. In a switch stand, the combination of a frame, a shaft rotatabletherein, an arm pivoted thereto and adapted to lock the shaft fromturning in the frame, and a lever havmg a slot through which the armextends,

said slot forming a cam which serves, as the lever is moved, todisengage the arm from the frame, the rest of the movement of the levercausing the arm to swing around and turn the shaft.

7. In a switch stand, the combination of a frame, a vertical shaftrotatable therein, an arm pivoted thereto and projecting substantiallyhorizontally therefrom, means upon the arm to engage with the frame, anda lever having a pear-shaped slot through which the arm extends, saidslot constituting a cam which, as the lever is moved, serves first todisengage the arm from the frame and then to turn the shaft through thefurther movement of the arm and permit the arm to engage the frame againupon the completion of its movement.

8. In a switch stand, the combination of a frame, a shaft rotatabletherein, an arm having one end forked, embracing the shaft and beingpivotally secured thereto, a projection upon the other end of the arm toengage with the frame, and means to disengage the projection from theframe and move the arm in a single operation.
